Perry met with the board Friday. He struggled for six seconds to come up with Sotomayor's name, then initially called the justice "Montemayor." A member of the newspaper's editorial board helped him out with the correct name.

He went on to criticize "eight unelected and frankly unaccountable judges." Nine justices sit on the Supreme Court. They are nominated by the president and confirmed by the Senate.

Similar gaffes have plagued Perry. On Thursday in South Carolina, he corrected himself after saying the U.S. is at war in Iran instead of Iraq.
